What Is Widcomm Bluetooth Software
Widcomm Bluetooth Software Windows 10
Installing WIDCOMM Bluetooth Stack v5.1.0.1100 on 32-Bit XP/Vista for Sony VAIO SZ:. Make sure the wireless switch is on and the Bluetooth LED is lit. Uninstall the existing Bluetooth stack and rename the bth.inf file located in%windir%inf to bth.inf.bak. If you're using the Microsoft Bluetooth stack, uninstall any Bluetooth related devices manually in the Device Manager (start-run-devmgmt.msc).
Restart Windows and during the startup it should detect an unknown device (UGX). Do not try to find or install the driver now., extract all the files to another location, and run the HTML file to watch the video of the remaining installation process.NOTE: Use an account that has Administrator privileges and disable UAC if you're on Vista.How to Uninstall:. Click Start - Settings - Control Panel - Add/Remove Programs (or Programs in Vista) and Uninstall the WIDCOMM Bluetooth stack. Watch this to complete the uninstallation. If you have a Bluetooth hardware ID different from what's shown in the video, you'll have to change the string that I had searched for in Notepad to what's shown in your hardware ID device properties.For instance, the hardware ID for the SZ4 Bluetooth is:USBVid044e&Pid300d&Rev1915USBVid044e&Pid300dSZ4 owners would simply need to change any instance of the USBVid044e&Pid300c string to USBVid044e&Pid300d in the btwusb.inf file.Also, when you delete the registry key during the uninstallation, make sure it matches your Bluetooth hardware ID. I don't think I had made that clear.
